Applicationled December 17, 1913. Serial No. 807,332.

To all whom t may concern:

Be it known that I, HARRY W. PIERCE, a citizen of the United States, residing at y Waverley, in the county of Middlesex and Another object of the invention is the pro` vision of means for compressing one end of the collapsibleink bag or reservoir as the pen point and its holder are projected, so that as the pen point and the holder are retracted, the compressed end of the collapsible ink bag or reservoir will expand, thereby causing a suction in the bag, so as to fully draw the ink from the pen point back into the bag.'

A feature of the construction of the pen is the provision of means for cutting oft' the supply of ink automatically yto the pen point as the holder of the point is retracted.y

In ypractical fields the details of construction may be subjected to alterations, falling within the scope of what is claimed.

The invention comprises further vfeatures and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings, Figure 1 is a perspective View of the improved fountain pen constructed' in accordance with the invention. Fig. 2. is a longitudinal sectional View through the pen, showingthe pen point and the holder proper therefor projected or extended. Fig. 3 is a longitudinal sectional view showing the holder proper and its pen point retracted. Fig. 4 is a sectional view of a fragmentary portion of the fountain pen showing the collapsible bag compressed. Fig. 5 is a detail perspective View of a portion of the fountain pen showing the compressing mechanism on one side of the pen and the means for locking the same. Fig. 6

is a fragmentary perspective view showing the other compressing mechanism lof the op-y posite side of the pen and the lock therefor. Fig. 7 is a sectional View on line 7-7 'of- Fig. 3. F ig. 8 is a sectional view online-5- 8-8 of Fig. 3. Fig. 9 is a detail view of the valve for cutting olf the supply of ink. Fig. 10 is a detail perspective view of one of the blades or plates with which the compressing mechanism coperates for compressing the ink reservoir or bag. Fig. 11 is a sectional view on line 11-11 of Fig. 2.

Referring more particularly to the drawings, 1 designates the outer casing of the fountain pen, which comprises two parts 2 and 3 threaded together as shown at 4. The part 2 of the casing 1 is constructed with guide grooves A circular head plate 6 is secured in one end of the part 2 of the casing by means of the screw 7. Swiveled or otherwise suitably mounted in the plate 6 as shown at 8 is'one end portion of the feed screw 9, which threads into the cross head 10, and by rotating the feed screw in one direction or the other the cross head will reciprocate, the reduced partsv 11 of the arms 12 of the cross head being guided in the guide grooves 5. The extreme end portion of the feed screw beyond the plate 6 has a turning head 13 secured thereto as at 14. By revolubly manipulating the tur ing head, a rotating motion is imparted to the feed screw. Passing through the arms 12 and securely locked thereto by the nuts 15 and 16 are rods 17. Fastened to two of the rods 17 by the nuts 18 is a transverse member or rod 19 which passes through the eyes 20 of the reservoir compressing plates 21, arranged upon opposite sides of the reservoir or bag 22. Arranged upon the interior of the casing 1 and secured thereto by the screws 23 is an enlargement wall 24 having a restricted passage 25, through which the contracted neck 26 of the reservoir or bag passes. As shown the end portions 27 of the bag compressing plates or members are curved or slightly directed toward each other. When the cross head is moved toward the outlet end of the pen moving the rod 17 therewith and also the member 19, the end portions 27 of the plates 21 (which are car' vadjacent the contracted neck to again eX- pand, thereby drawing or sucking the ink from the pen point, that is, after finishing the use of the pen.

Upposite walls of the casing 1 is constructed with elongated openings 30, and pivoted to said opposite walls as shown at 31 adjacent the interior of the casing 1 are levers 32 having rollers 33. These levers 32 are constructed so as to partially extend into the openings 30. Telescoped over the casing 1 is a sleeve 34 comprising two sections 35 and 36 telescopically joined together as at 37, there being screw pins 38 to 'hold the sections thus arranged. Upon the interior of the sleeve is a bead or rib 39 adapted to engage the rib 40 to limit the sleeve in one direction. The ends o'f the sleeve are provided with inwardly extending flanges.

' by the collapsible reservoir is compressed,

then when the sleeve is reversed in its movement quicklyl the plates 21 again separate, thereby permitting the'bag to expand, causin asuction therein, drawing the ink or Huid thereinto. The rib 40 of the casing 1 has two openings, one opposite the other and designated by the numeral 46 and 47. The shanks of the screw pins 38 are disposed in such positions relative to the rib or bead 40, so as to prevent the sleeve from being moved toward the pen point. However, to move the sleeve a slight partial revoluble movement is imparted thereto, sufficiently to bring the Shanks of the pins 38 in registration with the openings 47, then the sleeve may be moved, the pin shanks passing through said openings 46. In partially rotating the sleeve, the links 44 are sprung slightly, and when pressure (which is necessary to partially rotate the sleeve) is relieved andthe pin Shanks having passed through the openings 46 to one side or the otherof the bead 40, the links 44 assume their normal conditions, thereby restoring the sleeve to its normal position in a revoluble direction.

The rods 17 pass through the enlargement..

and are threaded at 49 into the wall of the inner casing 50. The portion 51 of the collapsible reservoir beyond the contracted neck 26 thereof is secured to the inner casing 50 over the bead 52, vby means o f the binding ring 53. Arranged on the interior of the part 51 of the reservoir is a spider frame 54 havingA a rod 55 terminating in a conical valve 56, which is designed to close the duct 57 of'theplug 58, thereby shutting off the flow or supply' of ink from the bag or.reservoir. The rod 55 passes through a 56 back from the duct 57, as soon as the casing 50 isfextended. This is accomplished owing to the spider spring 59 engaging the inner edges of the plug 58, the spider spring acting to spring backwardly as 50 and 58 are retracted, as the valve 56 is forced to close the duct 57. 'Then as the casing 5()v and 58 are extended, the spider spring 59 brushing against 58 will force 56 backwardly and allow ink to fiow into the duct 57. This spider spring also serves as a guide to keep the valve 56 always in a position alined with the duct 57. In practice, the interior of the casing 50, in a finished article or product is to be made as small as'possible, and yetl have room enough or space to permit of the reception of the spider spring, the valve 56, the valve rod 55 and the spider frame 54 so as to operate. l

On the rodv 19 is a coil spring '19a to cause and the duct 57 closed by means of the valvev 56. When itis desired to use the fountain pen the turning head 13 is rotated in the proper direction, which will cause the inner casing to be projected as well as the pen point, as shown in Fig. 2, the part 5l of the bag or reservoir being stretched as shown, and the valve 56 open, in which case the ink willA freely fiow from the reservoir through the inner casing 50, and through the pen point, through the/ duct '57 land feed duct -65. After having used the pen, the turning khead is reversed -in its movement, thereby retracting theinner casing 50, and as this is accomplished, the spider frame 54 first contacts with the' shoulder 66, and as the casing 50 is furthervretracted, the duct 57 is closed by the valve 56, when the casing 50 reaches its final normal'position as shown in Fig. 3. When projecting the inner casing 50 the parts 27 of the plates 21 compress the reservoir adjacent the contracted'neck 26, and when the inner casing 50 is retracted,'that portlonof the reservoir compressed by the parts 27vof the plates 21 again'expand, owing to .the parts 27 disengaging with the substantially inclined surface 28. In this manner the ink that is not used, but which tends to remain beyond the contracted neck 26 is again drawn into the body portion of the,

collapsible reservoir.

The invention ,having been set iforth,

` what is claimed as new and useful is point and a feed passage,`1neans for extend,

ing and reti-acting the inner pen section, and means for opemngand closing the feed passage tol the peu point automatically when the inner pen section is extended or retracted, and means for compressing a portion of the reservoir when the inner pen section is eX- tended so that as the ',i'nner pen section is retracted the reservoir will expand to suck the unused ink back in the reservoir.

In testimony whereofl I have signed my name to this specification in the presence of two subscribing witnesses.
